High Sun Resistant Staple Fiber 1.4D*38MM, UV Shield Functional
Polyester for Sportswear & Beach Fabric Product Overview Anti-UV Protective Polyester Staple Fiber 1.4D*38MM Specifications can be customized Product Description Our 1.5D*38MM moisture wicking quick dry polyester staple fiber is a mature functional textile raw material developed with permanent hydrophilic graft modification technology, specially produced for high-comfort sweat-management apparel and daily breathable textiles. It solves the inherent hydrophobic weakness of ordinary polyester fiber and realizes stable long-term sweat absorption and fast drying effect. Different from cheap surface-coated quick-dry fibers whose hydrophilic layer washes off easily, we integrate hydrophilic functional groups into the fiber molecular framework during melt spinning and post-treatment process. The moisture transport function is inherent and permanent, unaffected by frequent washing, bleach or softener use, which greatly improves the quality lifespan of end products and reduces customer return risks caused by faded quick-dry performance. Designed with professional capillary cross-section structure, each single fiber forms micro water guide channels. Once sweat contacts fabric inner side, liquid moisture is rapidly guided outward and dispersed for fast evaporation, so skin never stays soaked and sticky after exercise or daily perspiration. The 1.5D medium fine denier creates soft cotton-like handfeel, suitable for direct contact with human skin without harsh friction irritation. The standard 38mm fixed length ensures outstanding processing performance for spinning manufacturers. Uniform fiber length minimizes fly waste and thread breakage during high-speed spinning, lifting overall production efficiency. Flexible blending compatibility allows factories to mix this fiber with cotton, viscose or regular polyester to customize fabric softness, weight and production cost according to different product positioning. With stable low shrinkage and high tensile strength, textiles made from our staple fiber resist deformation, pilling and abrasion under regular wear and repeated laundering. The raw white fiber features high dye uptake rate, can be dyed into rich bright colors with stable color fastness for colorful sportswear and fashion activewear lines. We implement full batch quality inspection to guarantee consistent hydrophilic index, fineness and length for every shipment. Free lab samples are available for moisture absorption testing and spinning trial runs. Factory direct supply ensures stable stock capacity and competitive wholesale pricing for long-term global textile manufacturer partners, and we accept minor specification adjustments for large bulk orders.

Core Advantages 1. Permanent Hydrophilic Modification, Long-Lasting Moisture
Wicking Performance This fiber adopts internal graft hydrophilic modification instead of temporary surface coating treatment. The moisture-absorbing molecular chain is firmly combined with polyester substrate, so sweat wicking capability will not fade after dozens of repeated laundry cycles. Unlike disposable coated quick-dry fibers that lose function after several washes, our staple fiber maintains stable moisture management performance for the whole service life of finished textiles. 2. Powerful Capillary Sweat Conduction, Instant Dry Skin Feel Special irregular cross-section structure forms countless tiny capillary channels inside each filament. When skin sweats, moisture is quickly pulled away from body surface, transported to fabric outer layer and evaporated rapidly. It effectively eliminates sticky, damp and cold feeling after sweating, delivering constant dry and fresh wearing experience even during high-intensity exercise or hot weather. 3. 1.5D Medium Fine Denier, Balanced Softness and Structural
Strength 1.5D is a universal optimized denier for functional apparel. It delivers soft, smooth and non-irritating hand touch close to cotton, without the stiff rough feel of thick denier fiber. Meanwhile, it retains strong tensile strength and structural stability, resisting deformation during spinning, weaving and washing, perfectly balancing comfort and durability. 4. Standard 38MM Uniform Cut, Excellent Spinnability & High
Production Yield Precisely fixed 38mm cutting length with neat incision and stable length uniformity, few short fly fibers. The fiber bundle has good cohesion and fluidity, runs smoothly on all mainstream cotton and worsted spinning machines with low yarn breakage rate. It supports pure spinning into functional quick-dry yarn or blended mixing with cotton, viscose, regular polyester to adjust fabric texture and cost freely. 5. Low Shrinkage & Stable Dimensional Performance Finished by high-temperature setting craft, the fiber owns low boiling water shrinkage rate. Fabrics woven from this fiber will not shrink severely or deform after washing, maintaining original shape and size of sportswear, underwear and socks for long-term use, reducing post-production shaping loss. Frequently Asked Questions Q1: Is the moisture wicking effect permanent or just surface
coating? A1: It adopts internal graft hydrophilic modification, the function
is built into fiber structure instead of surface coating.
Performance remains stable after repeated washing cycles. Q2: What advantages does 1.5D denier bring compared to thinner or
thicker specs? A2: 1.5D balances soft skin-friendly touch and solid fiber
strength, it is the most versatile spec for sportswear, underwear
and socks, widely accepted by spinning factories globally. Q3: Can this fiber blend with cotton or other staple fibers? A3: Yes, it mixes evenly with cotton, viscose and regular polyester
to adjust fabric breathability, softness and cost freely. Q4: Will garments shrink heavily after washing? A4: The fiber is heat-set with low boiling water shrinkage,
finished fabrics maintain good dimensional stability after washing. Q5: Is the fiber easy to dye into bright colors? A5: Raw white fiber has excellent dye absorption capacity, supports
full color spectrum dyeing with reliable color fastness. Q6: Can I get free samples to test moisture absorption performance? A6: Small test samples are provided free of charge for lab
performance and spinning trials. Q7: What kinds of finished products is this fiber most suitable
for? A7: Mainly for sportswear, fitness wear, quick-dry underwear, sweat
socks, breathable bedding and functional sweat-absorbing nonwovens. Q8: Can you customize special denier or length for big orders? A8: Custom denier, length and hydrophilic strength can be arranged
for large volume bulk orders. Company Profile Guangzhou Octopus Fiber Co., Ltd. is a manufacturer, supplier and exporter located in Guangzhou, China.
